Harmonic Elimination in Solar Fed Cascaded Multilevel Inverter Using Optimization Techniques

摘要

In this paper, total harmonic distortion (THD) minimizationof the output voltage of multilevel inverters is discussed.Minimum Total Harmonic Distortion is one of the most important requirements from multilevel inverter concerning good Power Quality. This paper presents the optimization of THD in 15levels Cascaded Multilevel Inverter with equal dc source using Genetic Algorithm (GA). THD minimization is taken as an optimization problem derived. Results give all. Switching strategy, FFT analysis possible solutions at each modulation index and computational time has been analyzed using MATLAB simulation environment.
